I am entering Thailand through BKK on a single entry tourist visa and departing the same day from DMK airport for Cambodia ( I am only transiting but my flights are such that I have to go to another airport and hence exit BKK) . i reenter Thailand at Phuket International Airport after 3 days.
I would like to known at which airport do I need to get my passport stamped for reentry visa - at BKk or DMK. Also , are there any special requirements/documents needed ?
Thanks in advance
